4 au means 4 astronomical units

Explanation:

• AU (astronomical unit) is also a measure of length like centimeter, meter etc.
• The difference is that it is used to measure long distances like distance between planets and all..
• 1 AU is actually the distance between earth and sun.which is equal to

$1.495 \times {10}^{11} m$

• so,4AU means

$4 \times 1.495 \times {10}^{11}m \\ 5.98 \times {10}^{11}</strong><strong>m</strong><strong>$
